　　I would like to suggest that for sixty to ninety minutes each evening all television broadcasting in the United States be forbidden by law．

　　Let us take a serious, reasonable look at what the 1 might be if such a suggestion were- 2 ; families might use the time for a real family hour． They might sit 3 together after dinner and actually talk to one another． It is well known that many of our 4 －everything in fact, from the generation gap to the high divorce rate and to some forms of mental illness－are caused at least in part by 5 to communicate． By using the quiet family hour to 6 our problems, we might get to know each other better．

　　On evenings when such talk is 7 , families could rediscover more active pastimes． Freed from TV and forced to find their own activities, they might go out to take a 8 together to watch the sunset 9 they might take a walk together． 10 free time and no TV, children and adults might rediscover reading． There is more 11 in a good book than in a TV program． Scientists report that the generation growing up with television can hardly write an English sentence, 12 at the college level． Skill is often learned from reading． A more literate new generation could be a product of the quiet hour．
